Abstract
INTRODUCTION Endoscopic submucosal dissection (ESD) is a widely used technique to remove early neoplastic lesions. It was primarily used in the initial days to treat gastric lesions, but recently, the horizon of this endoscopic procedure has expanded, which has allowed us to manage other technically more complex locations, such as the colorectum. AREAS COVERED There has been an exponential growth regarding the wide range of devices available in the market for performing colorectal ESD. As a result, the aim of this review is to highlight the indication of this endoscopic technique, which device is best suited for which indication, as well as future trajectories in this field. EXPERT OPINION Although some devices have proven to be more advantageous than others in this area, very often the choice is still subjective, which is commonly attributed to individual preferences and experience. However, an accurate knowledge of the available tools and their functioning, with their pros and cons, is fundamental for any endoscopist venturing into the field of third space endoscopy. In this way, one can choose which device best suits a particular situation, along with simultaneously having the wealth of knowledge related to therapeutic armamentarium at our disposal in the endoscopy suite.

Chin Med J (Engl) 2022; 135:309-316. [PMID: 34999611 PMCID: PMC8812675 DOI: 10.1097/cm9.0000000000001840] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2021] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Endoscopic resection bleeding (ERB) classification was proposed by the authors' team to evaluate the severity of intraoperative bleeding (IB) during endoscopic submucosal dissection (ESD). This study aimed to evaluate the application of ERB classification and to analyze the risk factors of major IB (MIB) and postoperative bleeding (PB) associated with ESD for gastric neoplastic lesions. METHODS We retrospectively enrolled a total of 1334 patients who underwent ESD between November 2006 and September 2019 at The First Medical Center of Chinese People's Liberation Army General Hospital. All patients were divided into the non-MIB group (including ERB-0, ERB-controlled 1 [ERB-c1], and ERB-c2) and the MIB group (including ERB-c3 and ERB-uncontrolled [ERB-unc]) according to the ERB classification. Risk factors of major MIB and risk factors of PB were analyzed using a logistic regression model. RESULTS Among the 1334 patients, 773 (57.95%) had ERB-0, 477 (35.76%) had ERB-c1, 77 (5.77%) had ERB-c2, 7 (0.52%) had ERB-c3, and no patients had ERB-unc. The rate of PB in patients with IB classifications of ERB-0, ERB-c1, ERB-c2, and ERB-c3 were 2.20% (17/773), 3.35% (16/477), 9.09% (7/77), and 2/7, respectively. In multivariate analysis, proximal location (odds ratio [OR]: 1.488; 95% confidence interval [CI]: 1.045-3.645; P = 0.047) was the only significant risk factor of MIB. Chronic kidney disease (CKD) (OR: 7.844; 95% CI: 1.637-37.583; P = 0.010) and MIB (ERB-c3) (OR: 13.932; 95% CI: 2.585-74.794; P = 0.002) were independent risk factors of PB. CONCLUSIONS Proximal location of lesions was a significant risk factor of MIB. Additionally, CKD and MIB (ERB-c3) were independent risk factors of PB. More attention should be paid to these high-risk patients for MIB and PB.

Abstract
BACKGROUND Vonoprazan (VPZ) has the potential to prevent delayed bleeding and promote ulcer healing after endoscopic submucosal dissection (ESD) similar to proton pump inhibitors (PPIs). OBJECTIVE We aimed to evaluate the outcomes of VPZ-treated patients after ESD and compared the efficacy and feasibility in preventing a delayed bleeding and in healing an artificial ulcer after ESD between the VPZ and PPI therapies. METHODS This was a prospective, observation study in 11 Japanese medical institutions. We enrolled and evaluated 223 patients who underwent gastric ESD followed by VPZ treatment (VPZ group). We selected 385 patients who underwent gastric ESD followed by PPI treatment as historical controls (PPI group) to compare the outcomes between the VPZ and PPI groups using a propensity score matching analysis. RESULTS Among the 223 patients treated with VPZ, 173 were men and 50 were women with a median age of 72 years and with a median tumor size of 12.0 mm. Rates of en bloc resection and complete resection were 99.1 and 94.2%, respectively. Lymphovascular invasion was found in 6 (6.3%) cases. Intraoperative perforation and delayed bleeding occurred in 3 (1.3%) and 10 patients (4.5%), respectively. Scarring of artificial post-ESD ulcer was found in 153 patients (68.6%) at 6 weeks after ESD. The 205 pairs of propensity score-matched patients were comparable between the VPZ and PPI groups. The rate of delayed bleeding in the VPZ and PPI groups was 3.9 and 4.4%, respectively (difference, 0.5 percentage points; 95% confidence interval, -3.7 to 2.8%; non-inferiority, p = 0.01). Therefore, VPZ therapy demonstrated non-inferiority against PPI therapy in reducing the rate of delayed bleeding. The scar-stage ulcer at 6 weeks in the VPZ group and 8 weeks in the PPI group was 68.3 and 74.6%, respectively (p = 0.19). CONCLUSIONS VPZ therapy showed an efficacy and feasibility in preventing a delayed bleeding after ESD similar to the PPI therapy. VPZ for 6 weeks and PPI for 8 weeks were similarly effective for an artificial ulcer healing after ESD.

Abstract
Since the last decade, endoscopic submucosal dissection (ESD) has been used as the standard treatment for superficial gastrointestinal neoplasms. Trainees learning ESD frequently encounter difficulties such as vascularity, peristalsis, and fibrosis during the procedure. Because individual vascularity differs, it generally cannot be consistently avoided. Given that massive hemorrhages can prolong the procedure time and diminish treatment efficacy and that insufficient vessel handling may also increase postoperative bleeding, hemorrhage control during ESD becomes important to ensure procedure safety. This article discusses methods for controlling hemorrhage during gastric ESD. Endoscopists should have a basic understanding of the vascular architecture and the high‐density areas in blood vessels, which are susceptible to intraoperative hemorrhage. Efficient preventative coagulation should be performed in addition to mastering the techniques for hemorrhage control using hemostatic forceps. Techniques useful for preventing intraoperative hemorrhage at every step (e.g. submucosal injection, mucosal incision, and dissection) should be learned. Gaining procedural competence and learning hemorrhage control techniques not only during ESD but also in daily work would help provide safe and effective treatment.

Abstract
A woman in her 80s underwent endoscopic submucosal dissection (ESD) for a 20-mm-sized early gastric cancer lesion in the posterior wall of the upper gastric body. The lesion was resected en bloc with no adverse events. However, bleeding was observed in a post-ESD mucosal defect the day after ESD, so endoscopic hemostasis was performed. Moreover, hematemesis occurred 4 days after ESD, when the bleeding site showed a sign of pulsatile aneurysm. Therefore, endoscopic hemostasis was considered difficult, and angiographic treatment was chosen. Since angiography revealed a pseudoaneurysm in a portion of a branch of the left gastric artery, embolization with microcoils was performed. Thereafter, no bleeding occurred. To the best of our knowledge, there is no case report about the formation of a pseudoaneurysm in a post-gastric ESD mucosal defect. Thus, this case is being reported to document valuable information.

Abstract
Non-variceal upper gastrointestinal bleeding (NVUGIB) refers to blood loss from the gastrointestinal tract proximal to the ligament of Treitz due to lesions that are non-variceal in origin. The distinction of the bleeding source as non-variceal is important in numerous aspects, but none more so than endoscopic approaches for successful hemostasis. When a patient presents with acute overt blood loss, NVUGIB is a medical emergency, which requires immediate intervention. There have been major strides in pharmacologic and endoscopic interventions for successful induction and remission of hemostasis in the last two decades. Despite achieving tangible improvements, the burden of the disease and the consequent mortality remain high. To address endoscopic outcomes better, several new technologies have emerged and have been subsequently incorporated to the armamentarium of hemostatic tools. This study aims to provide a succinct review on novel technologies for endoscopic hemostasis.

Abstract
The present study aimed to evaluate whether second-look endoscopy (SLE) is able to prevent delayed bleeding after endoscopic submucosal dissection (ESD) of gastric carcinoma and to identify which types of lesion require SLE. ESD of gastric cancer at the early stage was performed on 210 patients between October 2014 and September 2016. Mucosal damage-associated bleeding within 24 h after ESD was considered as delayed bleeding. The association of the characteristics of patients and lesions, as well as surgical factors, with the incidence of bleeding as a measure of outcome was analyzed. A total of 110 patients with melena and/or hematemesis underwent SLE on the second day following gastric ESD. Within the entire cohort (n=210), late delayed bleeding (LDB) was defined as hematemesis or melena occurring following second-look endoscopy. Early delayed bleeding (EDB) was defined as hematemesis or melena occurring from the end of ESD to second-look endoscopy, or as active or possible bleeding at the time of the second-look endoscopy was reported in 17 (8.1%) and 20 patients(9.5%), respectively. The median interval between late delayed bleeding and ESD was one day (range, 1–10 days). The incidence of late delayed bleeding was significantly decreased in the SLE group compared with that in the non-SLE group (4.5 vs. 12%, P=0.028). Multivariate analyses revealed that ulcer, flat gross type, lesion diameter (>2 cm), the resected tumor size of >40 mm and Helicobacter pylori infection were independently associated with late delayed bleeding after ESD, while flat gross type, ulcer, the resected tumor size of >40 mm and artificial ulcer diameter >3 cm were independently associated with early delayed bleeding. Thus, the data of the present study indicates that second-look endoscopy following gastric ESD may be useful in preventing post-ESD delayed bleeding and should be performed on the second day.

Abstract
Non-variceal upper gastrointestinal bleeding (NVUGIB) is bleeding that develops in the oesophagus, stomach or proximal duodenum. Peptic ulcers, caused by Helicobacter pylori infection or use of NSAIDs and low-dose aspirin (LDA), are the most common cause. Although the incidence and mortality associated with NVUGIB have been decreasing owing to considerable advances in the prevention and management of NVUGIB over the past 20 years, it remains a common clinical problem with an annual incidence of ∼67 per 100,000 individuals in the United States in 2012. NVUGIB is a medical emergency, and mortality is in the range ∼1-5%. After resuscitation and initial assessment, early (within 24 hours) diagnostic and therapeutic endoscopy together with intragastric pH control with proton pump inhibitors (PPIs) form the basis of treatment. With a growing ageing population treated with antiplatelet and/or anticoagulant medications, the clinical management of NVUGIB is complex as the risk between gastrointestinal bleeding events and adverse cardiovascular events needs to be balanced. The best clinical approach includes identification of risk factors and prevention of bleeding; available strategies include continuous treatment with PPIs or H. pylori eradication in those at increased risk of developing NVUGIB. Treatment with PPIs and/or use of cyclooxygenase-2-selective NSAIDs should be implemented in those patients at risk of NVUGIB who need NSAIDs and/or LDA.

Abstract
BACKGROUND Although several studies have shown that second-look endoscopy does not affect the incidence of bleeding after gastric endoscopic submucosal dissection (ESD), the potential roles of second-look endoscopy have not been fully evaluated. This study aimed to determine the role of second-look endoscopy after ESD through a systematic review and meta-analysis. METHODS This study conducted a systematic literature search of MEDLINE, EMBASE, and the Cochrane Library through March 2016 using the keywords "second-look," "prophylactic hemostasis," "prophylactic haemostasis," "prevention," "prophylaxis," and "endoscopic submucosal dissection." Studies were included if they evaluated the incidence of post-ESD bleeding according to second-look endoscopy or prophylactic hemostasis during second-look endoscopy. RESULTS Four randomized controlled trials on post-ESD bleeding between second-look endoscopy and no second-look endoscopy and 12 non-randomized studies with a cohort design on post-ESD bleeding were included. On meta-analysis, second-look endoscopy did not affect delayed post-ESD bleeding (odds ratio [95% confidence interval] = 1.27 [0.80-2.00], I2 = 0%). During second-look endoscopy, patients who were considered as high-risk for post-ESD bleeding underwent prophylactic hemostasis. Delayed post-ESD bleeding was more common in patients who were treated with hemostasis during second-look endoscopy compared with those who were not (odds ratio [95% confidence interval] = 3.40 [1.87-6.18], I2 = 62%). In patients who underwent prophylactic hemostasis, the number needed to prolong a hospitalization period to avoid one additional post-ESD bleeding after discharge was 25. CONCLUSION Second-look endoscopy after ESD could not reduce the risk of delayed post-ESD bleeding. Delayed post-ESD bleeding was more common in patients who underwent prophylactic hemostasis than in those who did not.

Abstract
BACKGROUND Vonoprazan, a potassium-competitive acid blocker, is expected to improve the healing of endoscopic submucosal dissection (ESD)-induced gastric ulcers compared with proton pump inhibitors (PPIs). AIM To compare the healing status of ESD-induced gastric ulcers and the incidence of post-ESD bleeding between subjects treated with vonoprazan for 5 weeks and those treated with PPIs for 8 weeks. METHODS Patients in the vonoprazan group (n = 75) were prospectively enrolled, whereas patients in the PPI group (n = 150) were selected for a 2:1 matched historical control cohort according to baseline characteristics including gastric ulcer size immediately following ESD, age, sex and status of Helicobacter pylori infection. Two controls per case of vonoprazan-treated group were matched with a margin of 20% in terms of ulcer size and a margin of 5 years in terms of their age. RESULTS Although a higher number of completely healed ulcers was observed in the PPI group (95/150, 63.3%) than that in the vonoprazan group (14/75, 18.7%; P < 0.001), the ulcer size reduction rates, which were 96.0 ± 6.7% in the vonoprazan group and 94.7 ± 11.6% in the PPI group, were not significantly different (P = 0.373). The post-ESD bleeding incidence in the vonoprazan group (1/75, 1.3%) was less than that in the PPI group (15/150, 10.0%; P = 0.01). The factors affecting post-ESD bleeding incidence were the type of acid secretion inhibitor (P = 0.016) and use of an anti-thrombotic agent (P = 0.014). CONCLUSION Vonoprazan significantly reduced post-endoscopic submucosal dissection bleeding compared with PPIs.

Abstract
OBJECTIVE Elderly gastrointestinal bleeding (GIB) patients sometimes cannot be discharged home. In some cases, they die after hemostasis, even following appropriate treatment. This study investigates the clinical backgrounds and outcomes of elderly Japanese GIB patients. METHODS The medical records of 185 patients (123 men, 62 women; mean age 68.2 years; range 10-99 years) with GIB symptoms who underwent esophagogastroduodenoscopy or colonoscopy to detect or treat the source of GIB were retrospectively reviewed. We compared the outcomes between patients ≤70 (n=85) and >70 (n=100) years. The clinical backgrounds of the patients who died or changed hospitals to undergo rehabilitation or receive palliative care were evaluated, as were the association of four factors with these poor outcomes: GIB (re-bleeding or uncontrolled bleeding), endoscopic procedure-related complications, exacerbation of the pre-existing comorbidity, and any complications that were not directly related to GIB. RESULTS Of the patients ≤70 and >70 years of age, three (3.5%) and 17 (17.0%), respectively, were transferred to another hospital (p=0.003). One (1.2%) and five (5.0%), respectively, died (p=0.144). All three patients ≤70 years old that changed hospitals did so because their comorbidities became worse. The reasons for changing hospitals in the 17 patients >70 years of age included exacerbation of a pre-existing comorbidity (41.1%, 7/17), other complications (35.4%, 6/17), GIB itself (17.6%, 3/17), and endoscopic procedure-related complications (5.9%, 1/17). CONCLUSION Although non-elderly and elderly GIB patients had similar mortality rates, many more elderly patients could not be discharged home for various reasons.

Abstract
Endoscopic treatment has been accepted as first-line treatment of upper gastrointestinal bleeding, both for variceal as well as for non-variceal haemorrhage. Dual modality treatment including injection therapy with mechanical or thermal haemostatic techniques has shown superior outcome compared with injection monotherapy in non-variceal bleeding. During recent years, new endoscopic devices have been developed and existing endoscopic techniques have been adapted to facilitate primary control of bleeding or achieve haemostasis in refractory haemorrhage. For mechanical haemostasis, larger, rotatable and repositionable clips have been developed; multiple-preloaded clips are also available now. Over the scope clips allow to ligate larger vessels and can close ulcer defects up to 20 mm. Topical, easily applied substances withdraw fluid from the blood and thereby initiate blood clotting. This can be helpful in diffuse oozing bleeding, for example, from tumour or hypertensive gastropathy and has also shown promising results in variceal and arterial bleeding as bridging before definitive treatment is available. Radiofrequency ablation and multiband ligation have emerged as new tools in the endoscopic management of gastric antral vascular ectasia. In acute refractory variceal bleeding, a covered and removable oesophagus stent can provide tamponade and gain time for transport to an interventional endoscopic centre or for radiological intervention such as TIPS.

Abstract
Endoscopic submucosal dissection (ESD) for early gastric cancer is a well-established procedure with the advantage of resection in an en bloc fashion, regardless of the size, shape, coexisting ulcer, and location of the lesion. However, gastric ESD is a more difficult and meticulous technique, and also requires a longer procedure time, than conventional endoscopic mucosal resection. These factors naturally increase the risk of various complications. The two most common complications accompanying gastric ESD are bleeding and perforation. These complications are known to occur both intraoperatively and postoperatively. However, there are other rare but serious complications related to gastric ESD, including aspiration pneumonia, stenosis, venous thromboembolism, and air embolism. Endoscopists should have sufficient knowledge about such complications and be prepared to deal with them appropriately, as successful management of complications is necessary for the successful completion of the entire ESD procedure.

Abstract
Although techniques and instruments for endoscopic submucosal dissection (ESD) have improved, bleeding is still the most common complication. Minimizing the occurrence of bleeding is important because blood can interfere with subsequent procedures. Generally, ESD-related bleeding can be divided into intraprocedural and postprocedural bleedings. Postprocedural bleeding can be further classified into early post-ESD bleeding which occurs within 48 hours after ESD and late post-ESD bleeding which occurs later than 48 hours after ESD. A basic principle for avoiding intraprocedural bleeding is to watch for vessels and coagulate them before cutting. Several countertraction devices have been designed to minimize intraprocedural bleeding. Methods for reducing postprocedural bleeding include administration of proton-pump inhibitors or prophylactic coagulation after ESD. Medical adhesive spray such as n-butyl-2-cyanoacrylate is also an option for preventing postprocedural bleeding. Various endoscopic treatment modalities are used for both intraprocedural and postprocedural bleeding. However, hemoclipping is infrequently used during ESD because the clips interfere with subsequent resection. Bleeding that occurs as a result of ESD can usually be managed easily. Nonetheless, more effective ways to prevent bleeding, including reliable ESD techniques, must be developed.

Abstract
Gastric endoscopic submucosal dissection (ESD) causes artificial gastric ulcers and there is no consensus regarding the optimal perioperative management in terms of prevention of intra- or postoperative bleeding and promotion of healing. Traditionally, 8-week administration of proton pump inhibitors (PPI) and mucosal protective agents were used in the same way as for peptic ulcer management. However, recent studies have revealed that prior use of PPI might reduce intraoperative bleeding or early-phase postoperative bleeding, and combination of histamine-2 receptor antagonist (H2RA), and second-look endoscopy might have a similar effect on postoperative bleeding to PPI. Additionally, the advantage of PPI over H2RA is not proven and the optimal duration of PPI may be shortened until 2 weeks when the deteriorating factors for ESD ulcer are excluded. Furthermore, mucosal protective agents may facilitate ulcer healing. Further studies are needed to determine the optimal treatment protocol before and after ESD for both prevention of bleeding complication and promotion of ulcer healing, by using available antisecretory agents and mucosal protective agents.

Abstract
AIMS The life-time drinking profiles of Japanese alcoholics have shown that gastrectomy increases susceptibility to alcoholism. We investigated the trends in gastrectomy and alcohol dehydrogenase-1B (ADH1B) and aldehyde dehydrogenase-2 (ALDH2) genotypes and their interactions in alcoholics. METHODS This survey was conducted on 4879 Japanese alcoholic men 40 years of age or older who underwent routine gastrointestinal endoscopic screening during the period 1996-2010. ADH1B/ALDH2 genotyping was performed in 3702 patients. RESULTS A history of gastrectomy was found in 508 (10.4%) patients. The reason for the gastrectomy was peptic ulcer in 317 patients and gastric cancer in 187 patients. The frequency of gastrectomy had gradually decreased from 13.3% in 1996-2000 to 10.5% in 2001-2005 and to 7.8% in 2006-2010 (P < 0.0001). ADH1B*1/*1 was less frequent in the gastrectomy group than in the non-gastrectomy group (age-adjusted prevalence: 20.4 vs. 27.6%, P = 0.006). ALDH2 genotype distribution did not differ between the two groups. The frequency of inactive ALDH2*1/*2 heterozygotes increased slightly from 13.0% in 1996-2000 to 14.0% in 2001-2005 and to 15.4% in 2006-2010 (P < 0.08). Two alcoholism-susceptibility genotypes, ADH1B*1/*1 and ALDH2*1/*1, modestly but significantly tended not to occur in the same individual (P = 0.026). The frequency of ADH1B*1/*1 decreased with ascending age groups. CONCLUSIONS The high frequency of history of gastrectomy suggested that gastrectomy is still a risk factor for alcoholism, although the percentage decreased during the period. The alcoholism-susceptibility genotype ADH1B*1/*1 was less frequent in the gastrectomy group, suggesting a competitive gene-gastrectomy interaction for alcoholism. A gene-gene interaction and gene-age interactions regarding the ADH1B genotype were observed.

Abstract
Endoscopic submucosal dissection (ESD), an endoscopic procedure for the treatment of gastric epithelial neoplasia without lymph node metastases, spread rapidly, primarily in Japan, starting in the late 1990s. ESD enables en bloc resection of lesions that are difficult to resect using conventional endoscopic mucosal resection (EMR). However, in comparison to EMR, ESD requires a high level of endoscopic competence and a longer resection time. Thus, ESD is associated with a higher risk of adverse events, including intraoperative and postoperative bleeding and gastrointestinal perforation. In particular, because of a higher incidence of intraoperative bleeding with mucosal incision and submucosal dissection, which are distinctive endoscopic procedures in ESD, a strategy for endoscopic hemostasis, mainly by thermo-coagulation hemostasis using hemostatic forceps, is important. In addition, because of iatrogenic artificial ulcers that always form after ESD, endoscopic hemostasis and appropriate pharmacotherapy during the healing process are essential.

Abstract
Endoscopic submucosal dissection (ESD) is a novel endoscopic procedure first developed in the 1990s which enables en bloc resection of gastric neoplastic lesions that are difficult to resect via conventional endoscopic mucosal resection. However, given that ESD increases the risk of intra- and post-ESD delayed bleeding and that platelet aggregation and coagulation in artificial ulcers after ESD strongly depend on intragastric pH, faster and stronger acid inhibition via proton pump inhibitors (PPIs) and histamine 2-receptor antagonists (H(2)RAs) as well as endoscopic hemostasis by thermocoagulation during ESD have been used to prevent ESD-related bleeding. Because PPIs more potently inhibit acid secretion than H(2)RAs, they are often the first-line drugs employed in ESD treatment. However, acid inhibition after the initial infusion of a PPI is weaker in the early phase than that achievable with H(2)RAs; further, PPI effectiveness can vary depending on genetic differences in CYP2C19. Therefore, optimal acid inhibition may require tailored treatment based on CYP2C19 genotype when ESD is performed, with a concomitant infusion of PPI and H(2)RA possibly most effective for patients with the rapid metabolizer CYP2C19 genotype, while PPI alone may be sufficient for those with the intermediate or poor metabolizer genotypes.

Abstract
Electrocautery forceps with soft coagulation are actively used for treatment of bleeding and nonbleeding visible vessels during endoscopic submucosal dissection, but the usefulness of gastroduodenal ulcer bleeding has not been elucidated so far. The purpose of this paper is to elucidate the outcomes of electrocautery forceps with soft coagulation for peptic and artificial gastroduodenal ulcer bleeding. A retrospective multicenter study of consecutive case series during one year involved nine departments of high-volume hospitals in Japan. The study included 128 consecutive patients (62 with peptic ulcers and 66 with artificial ulcers) with bleeding nonmalignant gastroduodenal ulcers that were revealed using emergency endoscopy between January 2008 and December 2008. Hemostasis was carried out using electrocautery forceps with soft coagulation. Rates of successful initial hemostasis, rebleeding, transfer to surgery, and death according to peptic and artificial ulcer bleeding were recorded. Successful initial endoscopic hemostasis was obtained in 61 peptic ulcer patients (98.4%) and 66 artificial ulcer patients (100%). Rebleeding was observed in seven peptic ulcer patients (11.5%) and five artificial ulcer patients (7.6%). Rates of successful management with endoscopic methods alone were 96.8% (60/62) and 100% (66/66) in peptic ulcer patients and artificial ulcer patients, respectively. There were no severe complications or deaths related to the management of gastroduodenal ulcer bleeding. The novel endoscopic method using electrocautery forceps with soft coagulation for gastroduodenal ulcer bleeding seems to provide safety and efficacy that is comparable with that of endoscopic hemostasis with other established hemostatic techniques.
